Adult humans' understanding of support relations: an up-linkage replication.

In an up-linkage replication, three experiments examined adult humans' folk physics, i.e., their naturally occurring and spontaneous understanding of the physical world, using a violation of expectation (VOE) task and stimuli similar to those used to study chimpanzees', monkeys', and rooks' folk physics. Unlike what has been reported with nonhuman primates, adult humans did not look longer at physically impossible than possible events, though they did rate the physically impossible events as more interesting and novel than the possible events. These results underscore that behavior during a VOE experiment has many possible causes, only one of which may be a subject's folk physics.
